7pmJohn Terry starts on the bench tonight, with Di Matteo opting for the central defensive partnership of Gary Cahill and David Luiz.
7.02pmJuan Mata has overcome a hamstring injury to be named in tonight's starting lineup, and Branislav Ivanovic makes his 300th career appearance today, so well done to him.
7.08pmThese two teams have only ever met once before, and that was two weeks ago when Shakhtar won 2-1.
7.12pmShakhtar have never won on English soil; a run stretching four games. The best they have done is a 1-1 draw at White Hart Lane in 2009, when they advanced to the last 16 of the UEFA Cup 3-1 on aggregate and went on to win the tournament. Remember Vagner Love? Yeah, well he's still only 28 and playing at Flamengo, despite bursting onto the scene about a billion years ago.
7.24pmAs well as topping this group, the visitors are 12 points clear in the Ukrainian league with a 100% record from 14 games. And tonight is their 50th Champions League game. There's certainly a lot to be happy about in Donetsk at the moment.

7.34pmWe also have coverage of Manchester United's trip to Braga with Matt Law here, while Robert Summerscales is on duty for Celtic vs. Barcelona here.
7.43pmThe teams are making their way onto the pitch and we're just minutes from kickoff at Stamford Bridge.
5 minsAnd just when the Spaniard had missed a golden opportunity to score, he capitalises on a poor back pass to block Pyatov's clearance and give Chelsea the lead!
5 minsOscar had played a lovely ball from the left and Torres took too long to get a shot away and was closed down by Pyatov. Shakhtar tried to play their way out of defence and got it all wrong. Torres charged down Pyatov in a flash.
7 minsThe Spanish striker is really on his game tonight, as he skips past a challenge and shoots at goal, but Pyatov saves down low.
8 minsIt was a superb run by Fernandinho, as he weaved his way into the box and cut back for Willian, who found himself 12 yards out with a mass of players on the line, but found a way through.
12 minsShaktar are pressing forward now. They are looking rather lively and passing the ball very nicely.
13 minsCech spills a corner but Hubschmann can't capitalise. It's been an action-packed start at Stamford Bridge!
15 minsSHOT! Fernandinho forces Cech to make a save. It was sweetly struck but was palmed away.
15 minsA nice dummy from Torres creates half a chance but the Spaniard can't work Pyatov from a tight angle. Unlucky.
20 minsIt's been a terrific first 20 minutes at Stamford Bridge. Both teams look dangerous going forward and there's certainly more goals in this one.
21 minsSHOT! Adriano knocks down a long ball for Mkhitaryan to run onto but he blazes his volley wide.
22 minsMkhitaryan has a bit of space on the edge of the area but produce and air shot. Always embarrassing for a professional footballer, surely.
23 minsTorres nearly gets on the end of Ivanovic's cross but it's headed away from goal.
25 minsBoth teams are working extremely hard without the ball. It's great to watch and it looks like causing problems for the defences, but I can't see this pace lasting.
29 minsThere's no doubt that Shakhtar have come to win this game, because victory would see them qualify tonight. They have the tools as well, it seems. And with Juventus 2-0 up against Nordsjaelland Chelsea must win this game.
32 minsCLOSE! Some lovely build-up play sees Teixeria with a sight at goal, but his shot goes wide of Cech's goal. That was a fantastic move by Shakhtar!
UPDATE:Celtic are at it again. They are leading Barcelona 1-0 at Celtic Park.
33 minsA nervy moment in defence from David Luiz. Nothing new there, then.
35 minsTorres takes an ungracious tumble trying to backhell the ball to Hazard.
37 minsFantastic technique from Razvan Rat! He nearly finds Adriano with a volleyed cross from a long ball. that would have been some goal.
39 minsSrna gets in down the right once again and nearly finds Adriano with the cut back! Corner to Shakhtar...
39 minsChelsea scrambled the ball clear from Shaktar's corner and broke down field. Pyatov came well off his line to head the ball away and only succeeded in finding Oscar. The Brazilian found the back of the net from around 40 yards out. Superb technique!
42 minsShakhtar have not been deterred by that goal. They're coming forward again. Oscar's strike has reignited the contest and it's you attack/we attack again.
43 minsIt's been a fantastic game so far. Non-stop action. Oscar manages to craft half a chance, but Pyatov pushes his stabbed effort over the bar. Corner for Chelsea.
44 minsShakhtar's only weakness seems to be their goalkeeper. He is riddled with uncertainty and quite erratic.
44 minsAnother piece of sloppy defending from David Luiz nearly gifts Adriano a chance, but the danger is cleared.
8.34pmWell that first half has just flown by. It's been such a good game to watch, with plenty for both managers to be pleased about.
8.35pmDavid Luiz has been suspect at the back for the Blues, while Andriy Pyatov does not look all too secure between the sticks for Shakhtar.
8.38pmHis clearance made it easy for Torres to charge the ball down for the first goal, and he came so far off his line to head the ball away for the second goal, giving Oscar an open goal to aim at. The Brazilian still had a lot to do from well out, but managed to find the net with a beautiful strike.

8.47pmCeltic still lead Barcelona 1-0 at half time.
45 minsBut back at Stamford Bridge, Chelsea are ready to resume play for the second half.
46 minsGOAL! WILLIAN SCORES HIS SECOND OF THE GAME TO DRAW SHAKHTAR LEVEL ONCE MORE!
46 minsIt was a goal of absolute quality! Fernandinho split the Chelsea defence with a great ball for Srna, and the Croatian international squared the ball for Willian to strike past Cech at his near post! Simple yet brilliant.
53 minsSHOT! Rat smashes one from 25 yards out and it cannons off the post! Great effort!
55 minsChelsea's defending is so poor at the moment. Luiz is giving it away again. It's all Shakhtar and they're looking like the likely winners!
57 minsHazard is about to whip a free kick into the box...
58 minsIt evades everyone on its way out for a goal kick! Ivanovic was just caught a bit flat footed.
58 minsJohn Terry is warming up on the exercise bike on the sidelines. Let's face it, Luiz has to come off. He's been poor tonight.
61 minsAdriano is giving David Luiz the runaround.
64 minsAnd now it's the turn of Pyatov to rival David Luiz's bid to be tonight's worst performer. Another poor clearance, this time wit his foot, nearly gifts the ball to Hazard.
66 minsTorres wins a free kick on the edge of the area. Mata stands over it...
66 minsGOAL DISALLOWED! Mikel's header finds the net but the linesman correctly flags for offiside!
71 minsThere's a brief delay as Kucher is down receiving treatment. It's been the first real interruption of the night. the game has flowed wonderfully, and it's been an enjoyable one to watch.
72 minsTorres nearly gathers another Pyatov spill. Dodgy keeper.
73 minsPENALTY CLAIM!Ramires goes down under the challenge of Srna but but referee isn't interested!
75 minsCLOSE Rat's dangerous ball into the box is knocked behind for a corner.
76 minsThe corner is cleared but Shakhtar retain possession.
77 minsThe visitors have proven that the result two weeks ago was no fluke here tonight. A very impressive display indeed.
